Are these bulbs brighter than my VW Eos’s stock Headlight / Foglight bulbs?
No. Contrary to popular belief, aftermarket bulbs add color to your high beams / low beams / fog lights by adding a tint to the glass. This tint results in a nicer beam, but blocks out a small amount of light, resulting in a slightly dimmer beam than your stock clear Eos bulb would have. The color comes at the price of a LITTLE bit of brightness, but most people do not notice the difference.
